Berdasarkan analisis bivariat menggunakan uji statistik Wilcoxon, nilai ketiga instrumen (Nordic Body Map, Reaction Timer, Kelelahan Subyektif) diperoleh hasil p value 0,000 (p value < 0,05). Hal ini berarti bahwa terdapat perbedaan yang bermakna antara nilai rerata sebelum dan setelah intervensi. Kesimpulan. Kesimpulan penelitian ini adalah : (1) Pemberian Workplace Stretching Exercise dapat mencegah dan menurunkan keluhan muskuloskeletal.
